    Mat\u00e9riel:\u00a0<\/span>\u00a0<\/span><\/h2>\n
      \n
    • CD (Disque compact)\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Torche\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Ombre pour capter la lumi\u00e8re (p. ex. mur blanc)\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

      Instruction:\u00a0<\/span>\u00a0<\/span><\/h2>\n
        \n
      • Brillez sur le CD \u00e0 un angle d\u2019environ 45\u00b0\u00a0<\/span>\u00a0<\/span><\/li>\n
      • Tenez le CD de mani\u00e8re \u00e0 ce que la lumi\u00e8re r\u00e9fl\u00e9chie tombe sur l\u2019\u00e9cran\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

        Observation:\u00a0<\/span>\u00a0<\/span><\/h2>\n
          \n
        • En plus d\u2019un point lumineux blanc tr\u00e8s lumineux, vous pouvez voir un spectre de couleurs color\u00e9es.\u00a0\u00a0<\/span>\u00a0<\/span><\/li>\n
        • En outre, il peut y avoir un deuxi\u00e8me spectre qui est beaucoup plus faible. <\/span>\u00a0<\/span><\/li>\n<\/ul>\n

          Explication:\u00a0<\/span>\u00a0<\/span><\/h2>\n
            \n
          • Les sillons du CD agissent comme une grille \u00e0 travers laquelle passent les rayons lumineux de la lampe de poche.\u00a0<\/span>\u00a0<\/span><\/li>\n
          • Le point lumineux de la lumi\u00e8re est le principal maximum de la figure d\u2019interf\u00e9rence, le spectre color\u00e9 r\u00e9sulte des premiers maxima mineurs. En fonction de la fr\u00e9quence de la lumi\u00e8re, le premier maximum secondaire se trouve \u00e0 un endroit diff\u00e9rent.\u00a0<\/span>\u00a0<\/span><\/li>\n
          • Il est possible que le spectre des seconds maxima mineurs soit encore visible.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

            Conseil:\u00a0<\/span>\u00a0<\/span><\/h2>\n
              \n
            • L`espacement de la grille des sillons du CD est de 1,6 \u03bcm. Ces informations peuvent \u00e9galement \u00eatre utilis\u00e9es pour effectuer des mesures quantitatives ou des calculs. <\/span>\u00a0<\/span><\/li>\n<\/ul>\n","protected":false},"featured_media":1802,"template":"","meta":[],"product_brand":[],"product_cat":[970,885],"product_tag":[],"class_list":{"0":"post-1800","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-4-diffraction-interference-fr","7":"product_cat-c-optique-fr","8":"","9":"woocommerce-text-align-left","10":"woocommerce-image-align-center","12":"first","13":"instock","14":"shipping-taxable","15":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product\/1800","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/media\/1802"}],"wp:attachment":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/media?parent=1800"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_brand?post=1800"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_cat?post=1800"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_tag?post=1800"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
